Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, isolator spline of the present utility model, is made by 20Cr bar, and bulk strength is high, and anti-wear performance is good, comprises the spline body 1 being made up of bigger diameter end 1.1 and miner diameter end 1.2.
Be extrusion modling spline on spline for isolator of the present utility model, spline one-shot forming mould used comprises part of the upper die, part of the lower die and shedding mechanism.
Part of the upper die is made up of patrix 2 and the pressing mold 3 being loaded in patrix 2 bottoms, and pressing mold 3 forms the pressure hole 3.1 that internal diameter increases gradually from top to bottom, that is to say and has formed the pressure hole wall tilting.When work, take blame for others and be connected with hydraulic press in part of the upper die, taken blame for others and driven descending compacting by hydraulic press.
Part of the lower die comprises the barrel 4, die 5, upper cushion block 6 and the base 7 that connect successively from top to bottom, and barrel 4, die 5, upper cushion block 6 and base 7 are connected respectively fastening from top to bottom by bolt.When work, part of the lower die entirety is fixed on hydraulic press workbench.
Barrel 4 and die 5 are axially arranged with the bigger diameter end pilot hole 4.1 matching with bigger diameter end 1.1 shapes, size and the miner diameter end pilot hole 5.1 matching with miner diameter end 1.2 shapes, size successively.When work, isolator is supported in bigger diameter end pilot hole 4.1 with the bigger diameter end of spline, and lower footpath end is supported in miner diameter end pilot hole 5.1.
On die 5 sidewalls, be equidistantly provided with circumferentially the installing hole 5.2 that multiple one end are communicated with miner diameter end pilot hole 5.1, the other end runs through die 5 sidewalls, in installing hole 5.2, be provided with extruding drift 8.The inner of extruding drift 8 is molded into the extrusion head 8.1 matching with spline 1.3, the size that is the size of extrusion head 8.1 and the spline of required extrusion modling matches, the surface configuration of extrusion head 8.1 and the internal face shape of spline match, to squeeze out required spline in the time of extrusion modling.
The outer face of extruding drift 8 is molded into and the extruding inclined-plane 8.2 of pressing hole 3.1 inwalls to match, after this extruding inclined-plane 8.2 arranges, in the process of the descending compacting in part of the upper die, pressing mold 3 presses the oblique inwall in hole 3.1 to touch the extruding inclined-plane 8.2 of extruding drift 8 outer ends, the pressure hole wall of pressing hole 3.1 to tilt starts extruding extruding inclined-plane 8.2 and the extrusion head 8.1 that pushes drift is entered in miner diameter end pilot hole 5.1, now 8.1 of extrusion heads push the miner diameter end lateral wall being supported in miner diameter end pilot hole 5.1 gradually, thereby extrusion modling goes out required spline.
Material jacking mechanism comprises from top to bottom offseting is successively located at sleeve 9, push rod 10 and the lower jacking block 11 in cushion block 6 and base 7, and sleeve 9 tops offset to eject spline body 1 with miner diameter end 1.2 bottoms that are fitted in miner diameter end pilot hole 5.1.Be that sleeve 9, push rod 10 and lower jacking block 11 are from top to bottom located in cushion block 6 and base 7, and sleeve 9, push rod 10 and lower jacking block 11 offset by the top of lower jacking block 11 and the bottom of push rod 10, the top of push rod 10 offsets and is connected with the bottom of sleeve 9, like this in the time of work, be connected with the end cylinder of hydraulic press by lower jacking block 11, under the driving of end cylinder and under driving, jacking block is up, finally makes the top of sleeve 9 prop up the lower footpath bottom portion of spline body 1 and product is ejected to discharging.Certainly, before discharging, extruding drift 8 can be extracted installing hole 5.2 1 segment distances by manual mode, so that product eject smoothly discharging, on the extruding inclined-plane 8.2 of extruding drift 8, blind hole is set, one cross bar is installed in blind hole, the mode of hooking cross bar by hook just can easily be extracted a segment distance by extruding drift 8, the pull bar that certainly also can be connected with extruding drift in the interior setting of die 5, the structure being connected with cylinder piston rod by pull bar is extracted extruding drift automatically, these structures of extracting of extracting extruding drift are prior art, therefore do not describe in detail at this.
For further improving spline extrusion modling precision, in upper cushion block 6, spline plug 12 is also installed, the upper end of this spline plug 12 enters in miner diameter end pilot hole 5.1 through sleeve 9, between spline plug 12 and miner diameter end pilot hole 5.1 inwalls, forms miner diameter end entity container cavity.The setting of spline plug 12, in the process of miner diameter end extrusion modling, miner diameter end endoporus has the filling of spline plug 12, and spline plug 12 bears the extruding force of extruding drift 8, and extruding precision and the degree of accuracy of spline are improved greatly.
